Leaves alternate, sometimes opposite or clustered, simple.
Heads terminal, solitary or rarely clustered, pedunculate; involucral bracts in several series; receptacle flat or convex, naked. Ray florets many, in 2 or more series, female; style branches subulate to narrow-ovate, glabrous; achene fertile; pappus of several to many free, barbellate bristles or of capillary bristles more or less united in clumps. Disc florets bisexual but usually functionally male; style branches subulate or narrow-ovate, pubescent; achene sterile or rarely fertile; pappus of dimorphic hairs with both short and long more or less free, barbellate bristles or scales or else a cup of fused scales surmounted by 1–8 bristles, sometimes of uniform long bristles only.
